Napoli coach Rafa Benitez was delighted after his side's 2-0 win against Sassuolo on Monday.
The Partenopei's impressive run in 2015 continued with a convincing win against Eusebio Di Francesco's men as they showed that they are quality even without star striker Gonzalo Higuain.
The win means Napoli move to only two points from Roma ahead of next week's top-of-the-table clash between the Giallorossi and Juventus.
"Winning against Sassuolo was not easy tonight," Benitez said.
"We are eager to win games and be amongst the best this season but we're taking it one step at a time. Today we were fully focused on this game because they [Sassuolo] are incredibly organised and aggressive."
On Duvan Zapata, the Spaniard said: "We know how important he is to us.
"Having such a striker in the squad is a big advantage, we know how big of an asset he can me."
